What if a barely noticeable, unobtrusive tool could boost your email productivity and help you keep your schedule current? That’s the promise of Boomerang Calendar, a follow-up to the popular Boomerang email assistant from startup Baydin.

Boomerang Calendar, released Thursday in private beta, is a handy-dandy Gmail add-on that creates an intelligent link between your calendar and your inbox so that you never have to worry about double-booking again.

“Coordinating meetings over email has been a nightmare for years,” Baydin CEO Alex Moore told VentureBeat. “It takes too many emails to get something set up, and the process is fraught with mistakes. Boomerang Calendar is the first scheduling product that recognizes and embraces that email is the way we actually plan our agendas.”

The tool assists with calendar management in the inbox and uses artificial intelligence and natural language processing to detect dates and times in emails, visualize if you’re free or busy with color-coded links, and enable you to quickly add events to your calendars with a single click.

Users can also employ Boomerang Calendar to help them schedule group meetings with the “Plan a Group Event” feature. The feature lets the scheduler propose up to five times, specify attendees, and add a location. It then drafts an email to send to fellow participants, and participants can then select and submit the times that work for them. Boomerang Calendar manages real-time availability and responses in a separate email message where the meeting creator can pick and finalize a time.

Boomerang Calendar is the sibling of Boomerang, Baydin’s most popular email productivity product. Boomerang is an inbox assistant for Gmail and Outlook that helps email senders mark threads for future perusal, track responses, and schedule messages to be sent later on. The tool has been downloaded more than 1.1 million times.

Founded in 2010, Baydin went through the 500 Startups accelerator program last year and has raised $400,000 in funding. The startup makes money on premium upgrades and is said to be profitable. Baydin also makes a well-received inbox game, aptly named The Email Game, to encourage people to power through email messages.
